We celebrate Christmas with a reading of the story of the birth of Jesus.
God often chooses people who are doing in a minor way what He wants them to do in a major way. They are not the ones sitting and waiting for God to do something. They were doing what they could where they were and God came in and did the rest.
The whole Christmas message is about God sending a savior to preach, to heal, give sight and set free. It is hope to all and peace and good will to all who receive Him.
